GUARD FOR INCANDESCENT ELECTRIC LAMPS.

LOSQJLSS,

To all whom t may concern Be it known that we, CLAUDE A. LEI-L MAN and PERGY A. LAWRENCE, both citizens of the United States, and residents of Valparaiso, in the county of Porter and State of `indiana, have invented a certain new and useful Improvement in Guards for Incandescent Electric Lamps, of which the following is a specification.

This invention relates to Guards for incandescent electric lamps, of the type comprising a skeleton frame made of wire which incloses said lamp and protects the same from being broken by coming into contact with other objects.

In lamp guards of the type referred to, it is necessary to make provision for opening the guards for the purpose of inserting the lamps in the first instance, and for removing and replacing lamps which may be broken or burned out in use.

The object of the present invention is to provide a lamp guard of this general type in which the wires forming said guard are continuous from end to end thereof, and which comprises one or more wires which are removable in whole or in part, to provide for inserting the lamp into its socket and for removing same, together with means for detachably connecting said removable wires in position to close said guard.

To this end, a guard of our invention comprises the various features and 'details of construction hereinafter described and claimed.

ln the accompanying drawings, in which our invention is fully illustrated-Figure 1 is a perspective view of a lamp comprising a guard of our invention. Fig. 2 isa fragmentary sectional plan view on the line 2-2 of Fig. l; and Fig. 3 is a fragmentary plan view of my improved guard broken away in part to show the means for pivoting the guard wires.

Our improved lamp guards are particularly designed and especially adapted for use in connection with portable incandescent lamps, such as are used largely around auto-` Specication of Letters Patent.

mobiles and other machinery, and for purposes of illustration, we have, in the drawings, shown our improved guard as applied to such a portable lamp.

Referring now to the drawings, A designates, as a whole, a holder for the lamp, con* sisting, as shown, of a body portion l and a handle 2 for conveniently handling the same. Said holder A is preferably made of wood and is provided with a suitable recess in the end of the body portion secured in which is a socket 3 for an incandescent electric lamp indicated in dotted lines at 4, and formed lengthwise thro-ugh the handle 2 is a hole or opening indicated in dotted lines at 5 which communicates with the rear end of the recess in which the lamp socket 3 is secured.

In use, the conductor wires, not shown, eX- tend through the hole 5 in the handle 2 of the holder A into the socket recess in the body portion 1 thereof and are connected to the socket terminals, which are inclosed within said recess.

All of the foregoing features are old and well known and will be readily understood by persons familiar with the art without a more detailed description thereof.

The lamp 4 is inclosed within a suitable guard, designated, as a whole, B, and which is formed by wires 6, the upper ends of which are connected to a disk 7, simple means for this purpose consisting in forming screw threads on the ends of said wires which engage correspondingly screw-thread ed openings in the edge of said disk 7. At their lower ends, the wires G are connected to a ring 8 secured to the upper end of the body portion l of the holder A, as by screws orV the like. Excepting as hereinafter eX- plained, said wires 6 are preferably riveted or otherwise permanently connected to said ring 8.

To render the interior of the guard B accessible for the purpose of inserting the lamp Il therein and for removing said lamp therefrom when desired, one or more of the wires 6, as shown, the two wires designated G', are detachably connected to said ring 8 in such manner that, when detached therefrom, they may be turned or swung upwardly into the position shown in dotted lines, Fig. 1 of the drawings, thus providing an opening of suitable size through which the lamp 4 may be inserted into and removed from said guard B, in the manner desired.

In the preferable construction shown, the means for securing the lower ends of the wires 6 to the ring 8 are as 'ollows- Formed in the outer edge of said ring 8 are slots 9 which are adapted to receive the lower ends of said rods 6 when turned into position to complete the guard B, that is, to close the opening therein for the insertion and removal of the lamp 4. Said rods 6 are adapted to be locked in engagement with said slots 9 'by lmeans of a clip 10, which is mounted on the `upper surface of the ring 8 in such manner as to be movable endwise, as shown, by 'means of a screw 11, which extends through a slot 12 formed lengthwise in said clip 10, and is threaded into aV suitable hole or opening in the ring 8. The head of said screw overlaps the upper surface of the clip 1() at the edges of the slot 12 therein, thus securing said clip 'in operative position. Formed on the clip 10 are hooks 13 and 14, the hook 13 being formed by a slot 15 Vin the end of said clip and which is adapted to receive one of the wires 6 when in designed operative position, and the hook 14 being formed by a slot comprising sections 16 and 17, of which the section 16 is adapted to be brought into register with the slot 9 which is adapted to lreceive the second wire `6 and thus topermit engagement of said wire with said slot, and the section 17 corresponding substantially to the slot 15 and being adapted to receive said rod G when in designed operative position.

With the described construction, lit is obvious that, when the clip 10 is in lthe position shown in full lines, Fig. 2,'fthehooks 13.

and 14 will lock the removable guard Wire 6 in position and that, when said clip 'is moved into the position shown 'in dotted lines in said Fig. 2, the lower ends of said guard wires 6 may be withdrawn through the slots 9 in the ring 8 and swung or turned upwardly into the position shown in dotted lines in Fig. 1, thus forming an opening in the side ofthe guard B of sufficient size to permit the insertion and removal of the lamp 4.

IVhile we consider the means shown for securing the removable guard wires 6 in position to be preferable, other means for the purpose will readily suggest themselves to skilled mechanics, and we do not therefore desire to limit ourselves to the specific Vmeans shown.

Secured to the disk 7 is a hook 18 by means of which the lamp may be suspended from any convenient support.
